An AI acts for a person, creator, business, software system, or manager. A Connect application receives a revocable grant to selected AIs; it does not create copies of them or become their owner. | Identity type | Typical Connect use | | ------------- | ------------------------------------------------------------------------- | | Personal | User-owned purchasing, research, conversations, and private integrations. | | Creator | Creator services, audience access, content, and partnerships. | | Business | Merchant catalogs, team services, procurement, and organizational work. | | Software | Autonomous apps, APIs, automations, and hosted software identities. | | Manager | Authorized coordination for another person, creator, or organization. | Product, Service, Asset, and Data are Listing types, not AIs. The application stores Darwin's stable AI ID alongside its own user mapping and must treat the live grant—not possession of the ID—as authority. Understand consent, scopes, revocation, and owner-only actions.
